AEM 249 Lecture 15

What is a recursive function?

• A function that calls another function

• A function that has no else statement

• A function that has no base case

• A function that calls itself

What is the base case in a recursive function?

• The else statement containing recursive function calls

• The if statement referring to the end of the recursion

• The statement where the function calls itself

• The first statement in the function

What is the depth of a function?

• The number of if/else statements in a function

• The number of recursive calls made to a function

• The number of parameters in a function

• The number of print statements in a function

What is the purpose of the else statement in a recursive function?

• To contain the base case

• To end the recursion

• To print the final result

• To contain recursive function calls

What is the purpose of the if statement in a recursive function?

• To print the final result

• To end the recursion

• To contain the base case

• To contain recursive function calls

What is the purpose of the count parameter in count_down function?

• To determine the depth of the function

• To determine the base case

• To determine the number of recursive calls

• To determine the output of the function

What is the purpose of the print statement in count_down function?

• To determine the base case

• To contain recursive function calls

• To end the recursion

• To print the final result
